ton,- in the county .of Montgomery and State of Ohio, have invented certain new and useful Improvements in Combination Concrete Block and Brick Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same, reference being had ,to'the accompanying drawings, andto the figures of reference marked thereon, which form a part of this specification.

Thisinvention relates to new and useful brick machines. a v

The object of the invention s to proylde a machine of the above character whlcn has capacity for expeditiously molding concrete building-blocksor concretebricks of standard size. I

A further object of" the invention is to provide a machine of the above type which has a capacity for forming different thicknesses [of blocks with facility and to provide such blocks with 'difierent faces, or, in other words,

, different surface designs.

A further object of the invention is to provide a machine which is easily manipulated in both forming and delivering the block and I viewshowlngthe mold open.

which. avoids endangering'the block in any manner in delivering the same, all. as will usedin connection with Fig. 5 in making the mold, showing 7 7 making standard-size concrete bricks.

sponding equipment for making concrete blocks.

bricks. Fig. 7 is a detail perspective view of the tamp ing-plate utilized when making bricks. ig. 8 is a cross-sectional view of the same equipped for Ina detail description of the invention similar referencecharacters indicate correarts. i

I will st describe the apparatus inits =1 and 2 designate the lower and upper framework, the lower framework consisting of standards which are j oined at their upper ends in a solid portion 1, which supports the upright rear side 3 and ends 4 of the mold.

These rearward and end walls 3 and 4 are rigidly united by being bolted together and to the upper solid portion 1 of the frame work, forming a support forthe mold. These rearward and end walls 3 and 4 are therefore at all times stationary, and this is an im portant feature in that it enables the completed blocks to be removed from the mold without endangering the same' 7 is the faceplate, which forms the bottom of the mold in the formation of the concrete block. This face-plate is rigidly secured to a suitable number of brackets 8for example, two of such bracketsand these brackets are rigidly secured to the frontside plate 9, which is hinged at 10 to the end plates and will be again referred to. As the face-plate 7 is shown in Fig. 4 it is designed to produce a rook-face to the block when finished; but it will be understood that such bottom plate may be provided with any surfacejthat'it is desired to impress upon the face of the block,

either smooth surface or any ornamental sur-' face. The thickness of the block may be decreased to from two to four inches by elevating the bottom-of the mold or the face-block 7 within the mold, thus decreasing the depth of said mold. ,This is accomplished by mov-',

ing the supporting-brackets. 8 to a higher position and uniting them to the front side wall 9 by passing the securing-bolts 11 through the openings 12 in said front side wall. These blocks of less thickness-are used merely as facing or veneer blocks in some instances and do not take the place of the main blocks of the building.

It will be'understood that the face of the block is not changed whether the block is reduced in thickness by elevating the bottom -of face-plate 7 or whether said face-plate is in a position to forma building-block of maximum thickness.

Owing to the brackets 8 being attached to the front side plate 9 and the bottom or face plate 7 being attached to the said brackets, it will be seen that when the mold is open, as in Fig. 8, the finished block is delivered with its outer side down upon the pallet 13; The bottom or face plate'7 at this time lies in the rear in a vertical position, and the block is I removed awayv from the face-plate without endangering the face formation thereof. 14 represents end -plates,which are hinged V of said face-plate.

at 15 to the front side plate 9 and are adapted to fit in the mold against the ends 4 when the front side plate 9 is elevated to a vertical position, as in Fig. 4. When said front side plate 9 is opened upon the pivots or hinges 10, these end plates 14 are swung outwardly, as shown in Fig. 1, to clear the ends of the block and permit said block to be removed upon the pallet, 13. The pallet 13 has se cured to it cleats 16, which rest upon the front side plate 9 and afford suitable space below said pallet for the hands to secure a hold upon the pallet in removing the same with the finished block. The pallet 13 incloses the outer edge of the bottom of the mold or the faceplate 7, while the rearward wall 3 of the mold incloses the rearward edge The hinged end lates 14 have cores 18 secured thereto, whic form a semicircular vertical groove in the ends of the block. One of these end plates 14 is shown without a core 18. This is the case when one end of the block is exposed at the corner of the wall built up by these blocks. In the case of all of the blocks whose ends are inclosed by the abutting ends of the adjacent blocks two such cores 18 are used to provide the necessary space for the application of cement in building a wall. The outer edges of the stationary end walls 4 are rounded, as at 4. These rounded edges act as cams to throw inwardly the hinged end plates 14 when the front side wall 9 is being elevated upon its pivots 10 to close the mold preparatory to the formation of a block. The front side wall 9 is provided with two locking-notches 9, which receive keys 19, serving to look said.

front wall in its upright position. These keys 19 are pivoted to the outer sides of the end walls 4 at 20, and on the outer ends of said keys there are pivoted at 21 handles22, by means of which the keys 19 are swung into the notches 9. At the pivots 21 there are eccentrics 23, which engage the outer side of the plate 9 when the handle portions 22 are moved parallel with the plate 9, or nearly so. These eccentrics 22 thus serve to hold the front side plate 9 rigidly in its upright position. i

The upper surface of the block within the mold is tamped by a tarriping-plate 24, carried upon arms 25, pivoted at 26 to brackets 27, rigidly attached to the rear wall 3 of the mold, Joining the upper ends of the arms 25 is a handle 28, which is grasped by the hand in lowering the tamping-plate 24 to tamp the concrete within the mold in the formation of the block.

29 represents two resilient arms, which are rigidly united at the lower ends to the rear wall 3 of the mold and have a suitable seat 30 to receive the journals of the handle 28 to support the t'ampin -plate in an elevated position when out 0 use. In elevating the tamping-plate to this position the seat 30 readily enters below the ournals of the handle, owing to the resilient nature of the arms 29.

In order to relieve the brackets 8 of undue strain at a point farthest from their points of attachment with the front side plate 9, I provide means for engaging the rearward portion of the bottom or face plate 7. This means consists of an adjustable member 31, which is slotted to receive a screw 32. This screw engages a stationary projection 33, extending from the rear wall 3 of the mold, and by this means the member 31 is secured in position with its upper end abutting against the lower side of said face-plate 7 at the extreme rearward edge of said face-plate.

I have thus far described my improved concrete-block machine when utilized for molding concrete blocks of various sizes, and it will be understood that the inner surfaces of the end plates 14 may be provided with rock-face surfaces or any other surface that it is desired shall be impressed upon the ends of the block. It may be also stated in con.- nection with these end plates 14 that the cores 18 are detachable and may be united to said end plates in the center of said plates or on either side of a center line, and thus the recesses in the ends of the blocks may be placed at desirable points.

Tln'ough the instrumentality of the parts illustrated on sheet 4 of the drawings the machine is transformed into a machine for making in one operation a series of bricks of standard size. For this purpose the depth of the mold is decreasedby placing therein a series of base-plates 5, which are in the form of brackets with upper smooth surfaces and intervening spaces 6. The base plates or brackets 5 are rigidly attached to an inner plate 17 by means of bolts 34, said inner plate 17 being bolted through openings 35 to the upper portion of the front plate 9. will thus be seen that the plates or brackets 5 are ri idly united to the supplemental plate 17, which in the present instance takes the place of the pallet-board 13, and said plate 17 is rigidly united to the hinged plate 9, so that the plates or brackets 5, upon which the bricks are supported, are moved upwardly and outwardlyto deliver the bricks.

36 is a rearward interior plate which supports a series of division-plates 37, which enter the spaces 6 between the bottom plates or brackets 5, and thus separate the mold into a series of uniform individual molds. This rearward plate 36 is rigidly secured to the rearward wall 3 of the mold by a suitable number of bolts 38, so that said plate 36 and the division-plates 37 are held stationary when the bottom plates or brackets 5 are being moved upwardly and outwardly between said division-plates. The front side plate 9 is constructed of two parts, which are united on the line 39 by hinges 40. When the machine is used for molding a series or bricks,

sition toremove the molded block, which is the upper hinged section 'of said front side i I" plate 9; is lowered upon'the hinges40 to deliver the brick. The lower section of said wall 9 is united to the endwalls 4 of the mold by a suitablenumber ofscrews 41, whichpenetrate openings 41' and secure said lower portion of said wall 9 rigidl-yto the end walls of the TOi mold, The inner supplemental wall 17, 'asbefore stated, is secured -by screws entering openings 35'. These screws penetrate openportion of said wall or'plate 9,. a When themold is used for forming blocks, the two portions of the front sidewall 9 are -ma'de rigid at the hinged joint ,39 by cleats 42, which are rigidly attached to said parts Qand'cross the -hinged joint, so that'thefront side wal-lu9 beoomes one rigid part,'which is opened-outwardlyupon the pivotslO.

43 is anoperating-rod which is utilized to elevate'the front side wall 9 and to afford a 'supporaasshown' in Fig. 2, when said front e plate 9 is lowered to'a horizontal po- 'supported thereon by the pallet-board 13.
